My invention relates to door operating mechanisms, and it is particularly relatedto a device for opening doors which may be operated ata point remote from the door itself. i I

, I In my Patent No.- 1,265,229, I have disclosed a door opening mechanism which may be used advantageously in combinationwith garage doors or the'like, whereit is desirable that the driver be enabled to operate the door without alightingfrom the carriage.

The present invention has for its objects theprovision of certain improvements over the original embodiment, whereby greater smoothness of operation and simplicity of construction is realized;

More specifically, the obj ects'rof my inventionreside in improving the operating' characteristics of the] door interconnecting bar,

H whereby the doors may be actuated :with

greater freedom -and independence of movement, yet atthe' same timecoaction' between said doors is betteredthereby. m i

, Other improvements in the door actuating mechanism havebeen devised for the purpose ofdistributing the components of force applied thereto more advantageousl gwith the view atall times of maintaining the-required force as small-as possible. a

These andoth'er objects will be more apparent and a better understanding of my invention may be had, by-referringto'the draw ,ingswhichfform apart of the specification in which Q Fig. 1 is a perspective "view of one form which my invention ,may assume;

Fig. 2 is a plan view illustratingthe relation ofvthe elem-entfwheii the doors areiin a ture illustrated in Fig. 3. w

substantially on the line V.V-of Fig; 3. i Fig. 6 is a cross-sectional view through the connection for illujs'tratingits compressible telescopingcharacteristics. v 1 In practicing my invention, I provide a vertical frame structure 11, which forms the pivotal supports for 'twocomplementary doors 12 and 13. a A -V-shap'ed"member- 14, having its ends bolted to the building-structure together'with a vertically, inclined central member 16 likewise bolted-at one end to the building structure 11 and connected at'the other end to the ape); ofthe Veshaped member 14, constitute theframe of the door operating mechanism.- 'The frame may be. lengthened or otherwise adjustedin'order that the same device may be 'em'ployed?with doorsofanysize. I A vertically disposed pin 17," having a lower bifurcated extremity, is' pivotally mounted in the frame at the junction of the 'V'-shapedmember and the inclined member. 7 Across pinl8 isdisposedin the bifurcated portion of thevertical member -17, from which is pivoted one link 19"ofa-dual armed toggle mechanism 21'' A plurality "of oppositely disposedapertures 22 areprovided in the arms of the link 19 for thepurpose of accommodating a pin 23 from Which one end of'a complementary" link 24 of the toggle mechanism 21 is pivoted. The other endof the link isforked and is, pivotally joined I i over a pulley that is-bracketed from the incline'd ,memb'er 16. From this pulley the cable is conducted to. an "auxiliary? pulley 32 3 thatis securedto the wall structure; "Obviously 1t*may be conducted infany direct1on desired'where it will be 'mostconv en} .ient and serviceablelfor the e eeate i-y In order"tl 1at the); doors 3 may" {be opened coact1ve1y, a bar mechanisni'gois provided which consists-atti e relatively show red 36 3D that is pivotally secured at one end to the door. 12, and adapted to swing in a horizontal plane. A short pin 37 is transversely disposed, and rigidly secured in the pivoted rod 36. A hollow rod 38 which is provided with a slot 39, to receive the pin 37, is pivotally bracketed from the other door and contains a portion of the rod 36. lVithin the hollow portion thereof, a coiled spring 41 is lodged which urges the rod 36 outwardly,

and the transverse pin 37 into en agement Wit-h the end of the slot 39. This portion of the machine is likewise of an adjustable construction, and is adapted to be employed with doors of widely different dimensions.

The doors are-urged into an openor closed position by means of a spring mechanism 43, that consists essentially of a rotatable pulley 44,;having a vertical axis that is mounted upon a bracket member 45, which is bolted to the door. The pulleyengages the inner surface of an arcuate member 46 which is pivoted atone end from the wall ll, whereas the other end is interconnected with the wall by means of a coiled spring 47. The configuration of the arcuate member is such that the spring 427 is tensioned most when the door; 12 is substantially.perpendiculartothe wall 11.. A slight pivotal movement of the door from this position either in one direction or the other, will enable the spring to relax, thereby either opening, the door completely or closing the same. 7 a Q 1 To open the doors from a closed position requires only that; the cord or cable 31 be pulled outwardly, thereby pivoting the links of the 'toggle member 21 upwardly. Only the door 12 isat first actuated but after the transverse pin 37 engages the end of the slotted portion of the hollow rod 38, the movementv becomes coactive and the doors are opened simultaneously. At the same time, the pulley member 4A rides the surface of the pivoted arouate member, tensio ning the spring47 until the door has turned through an angle of 90. After it has reached a position sli htly beyond 90, additional movement v o the cable is unnecessary in that the spring member 47 will not only complete the pivotal movement of the door 12 by reason of its contracted force, .but will simultaneously complete the pivotal movement of the complementary door 13 through the agency of the-telescoping bar member 35.

.It willbe observed that the compressible character of the bar'result's in a greater freedom and smoothness of operation; furthermore, the extended link of the toggle member not only facilitates the opening operation in. that it afl'ords. a greater and ,desirablelever. action, but it'tends also to lessen the necessary force which must be' applied.

While; Ihave described but a single em- 7 bodiment of the-primeiples ofzmy invention,

and have illustrated but one form which it may assume, it will be apparent to those skilled in the art that they are susceptible to numerable modifications, and I desire therefore, that the invention be limited only to accord with the prior art, in the appended claims.

-Having thus described my invention, what I claim, and desire to secure by Letters Patent is:

1. The combination with a vertical support having two complen'ientary door members hinged therefrom; of a door operating mechanism comprising a frame relatively stationary with respect to the pivotal door member; two link mechanisms pivotally and rotatably oined to the frame and one of the doormembers respectively, one link being pivotally joined intermediate the ends of the second link; the free end of said second link extending across the path of movement of said first link; means secured to the free end of the second link for manipulating the links; and means interconnecting the doors for effecting coactive movement therebetween. r i

2. The combination with a vertical support having two complementary door members hinged therefrom; of a door operating mechanism comprising a frame relatively stationary with respect to the pivotal door members; two link mechanisms pivotally and rotatably joined totheframe and one of the doormembers respectively; one link being pivotally joined intermediatethe ends of the second link; the free end of said second link extending across the path of movement of said first link; means secured to. the free end of the second link for manipulating the links; and a resilient member pivotally joined to one of the doors and pivotally bracketed to the other door adapted to of fect coactive movement between the doors.

3. The combination with a vertical support having two complementary door members hinged therefrom; of a door operating mechanism comprising a frame relatively stationary with respect to the pivotal door members; two link mechanisms each of which are pivotally and rotatably joined to the frame and one of the door membersre spectively; one link being pivotally joined intermediate the ends of the second link; means secured to the free end of the second link for manipulating the links; means inter connecting the door for effecting coactive movement therebetween and a member pro vided with a cam surface having one end piv otally joined to: the support, the other end being resiliently maintained in operative position. V 5 i In testimony whereof, I aflix my signature.
